Title:
PHOTO-CURING TYPE 3D FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/164642
Kind Code:
A2
Abstract:
The purpose of the present invention is to provide a photo-curing type 3D forming device enabling a formed article, which is being cured in a resin tub, to move relatively stably without being damaged in spite of the photocuring reaction heat of a photo-curable resin and operation fatigue. To this end, the photo-curing type 3D article forming device according to the present invention comprises: a resin tub; a photo-curable resin layer formed of a photo-curable resin, and accommodated in the resin tub so as to form a layer; a release layer formed of a non-curable flowable material having a gravity different from that of the photo-curable resin, and having a releasable surface contacting the photo-curable resin layer, and accommodated in the resin tub; a forming plate accommodated in the photo-curable resin layer so as to support the formed article; an elevating driving unit for elevating the forming plate and/or the resin tub such that the forming plate can come close to or be spaced apart from the releasable surface; and an image light emitting unit for emitting image light at the photo-curable resin layer by penetrating the release layer.
